Jar of dreams

The Jar of dreams is a members-only Old School RuneScape item — “With this jar, your dreams can come true!”. Its Grand Exchange buy limit is 4 per 4 hours. Right now it buys at 2,025,000 gp and sells at 2,400,000 gp — a net margin of 327,000 gp (16.1% ROI) after the 2% Grand Exchange tax of 48,000 gp. High alchemy yields 1 gp.

To flip it, place a buy offer near 2,025,000 gp and a sell offer near 2,400,000 gp; the spread minus GE tax is your profit. Confidence figures are model estimates from live OSRS Wiki prices, not guarantees — flip responsibly.
